When the lahar stops moving it creates a layer of volcanic depris‚ (which can contribute to the pryroclastic debris). 3. Describe the differences among shield volcanoes‚ strato- volcanoes‚ and cinder cones. How are these differences explained by the composition of their lavas and other factors? Shield

The Precambrian-Cambrian Boundary In the history of the Earth geologists study events in the geologic time scale and fossil record to gain an understanding of the structural and biological history of our planet. One of the debated and studied areas of Earth’s history is the sudden occurrence of multicellular hard-shelled organisms from soft bodied and single celled organisms in the Precambrian-Cambrian boundary. The debut of hard parts in the fossil record is believed to have occurred 570 million
